Look in your documentation on how to recover the hard drive in case of OS problems. Most likely your netbook came with a recovery partition on the hard drive which will restore your netbook back to factory condition. You would have to boot to this recovery partition and follow the prompts.
Thank you, I look at the manual it say use external usb drives. is it possible to make an usb jump drive bootable?
